On x86 the remainder is a by-product of the division itself so any half-decent compiler should be able to just use it (and not perform a `div`

again). This is probably done on other architectures too.

Instruction:

`DIV`

srcNote: Unsigned division. Divides accumulator (AX) by “src”. If divisor

is a byte value, result is put to ALand remainder to AH. If divisor

is a word value, then DX:AX is divided by “src” and result is stored

in AXand remainder is stored in DX.

```
int c = (int)a / b;
int d = a % b; /* Likely uses the result of the division. */
```
